About
Super Duper Amy Freaking Rose is a free fan-made Sonic platformer starring Amy Rose, who must recover her stolen birthday cake from Witchcart before the night ends. Made by fractalcherries and shown at SAGE 2025 (the Sonic Amateur Games Expo), it runs about 15 minutes across five 2.5D levels capped by a boss fight. It draws on the Sonic Advance and Sonic Battle look, and was well received for its sprite art, music, and fast but forgiving level design. As an unofficial fan game it is not a SEGA product, was never sold commercially, and the developer has marked it complete with no further content planned.

⚙ Setup notes
Game: Free 2.5D platformer Sonic fan game by fractalcherries (Witchcart steals Amy's birthday cake), shown at SAGE 2025. Short (~15 min, 5 levels + boss).
Engine: Built in Construct 3; the Windows download is an NW.js wrapper (Chromium-based), which runs well under Proton.
Proton: The Windows .zip build (Super Duper Amy Freaking Rose (v1-1-0 Windows).zip) runs under Proton on Deck — GE-Proton is the safe pick for the NW.js/Chromium build. Not on Steam, so no ProtonDB report exists.
Controller: Native gamepad input works; if the Deck controls don't bind, force a Gamepad (with Joystick) Steam Input layout. Note: a button-swap (Homing Attack / Light Speed Dash) was reported in the browser/HTML5 version on Firefox — another reason to prefer the Windows build.
Install: Add the unzipped Windows folder as a non-Steam game and point Steam at the .exe. Prefer this downloadable Windows build under Proton over the in-browser HTML5 version, which had controller-mapping quirks on Linux.
The one thing to know
Supply your own copy: Free fan game (not SEGA / not for sale), distributed via itch.io and Sonic Fan Games HQ.
Not on Steam: Never on Steam, so steam_appid stays empty and no ProtonDB entry exists.
Binary: Built in Construct 3 (NW.js Windows export); the .exe is named after the game title. If the exact name inside the v1-1-0 Windows .zip differs, point the binary at whatever launcher .exe the archive contains.
Install: Prefer the downloadable Windows build under Proton over the in-browser HTML5 version, which had controller-mapping issues on Linux.
Links: deckport links nothing.

Get the artwork
deckport never hosts game images. Open this game on SteamGridDB, pick
the cover / hero / logo / icon you like, and drop them into the
game folder under .deckport-art/ before you push it to the
Deck. The importer files them under the right names automatically.
Run it on your Deck
Two files: the one-time importer (deckport.py) in your
Deck's home folder, and this game's install helper. Copy the game
into ~/Games and run the helper with Steam closed — it
writes the recipe (binary, launch options, Proton version)
and registers the shortcut with artwork.
